Embodiment 1
[0031] A construction method for one-time in-place construction of pipeline steel casings in building shafts, which is carried out according to the following steps:
[0032] (1) In the construction preparation stage, analyze and study the construction drawings, clarify the number, pipe diameter and size of the casing used for each pipe riser in the shaft, and consider the overall thickness of the wall, the stucco layer, and the position of the bracket On the basis of the valve size and pipeline maintenance factors, the scientific positioning data of the distance between the casing and the wall and the mutual distance are formed, and then simulated on the computer, and then the overall installation plane positioning diagram of the casing group is formed;
[0033] (2) According to the positioning dimensions of the overall installation plane of the casing, make the overall positioning mold 5 of the casing group with thin wood or other hard plates;
[0034] (3) With the aid of the...

Abstract
The invention discloses an integral setting and one-step in-position construction method for steel sleeves of inner pipelines of a vertical shaft of a building. The integral setting and one-step in-position construction method includes drawing an integral installation planar positioning graph of sleeve stacks; manufacturing an integral positioning mold for the sleeve stacks; accurately placing the sleeves and integrally welding the sleeve stacks in advance; reserving the first-layer sleeve stack by a measuring process by the aid of a straight scale; projecting positions of center points of first-layer reference sleeves to bottoms of formworks of layers to be positioned by a laser positioning process and marking corresponding points of the bottoms of the formworks; displaying positions of center points of sleeves to be positioned on upper portions of the formworks by a process for nailing the formworks at the marked points by iron nails or a process for drilling holes at the marked points of the formworks; placing and fixing a certain sleeve stack according to the positions of the center points of the sleeves to be positioned; and sequentially placing and fixing the remaining various sleeve stacks by such analog to complete integral setting and one-step in-position operation for the various layers of sleeve stacks. The integral setting and one-step in-position construction method has the advantages that construction is easy and convenient, secondary form erecting and pipe hole pouring are omitted, the construction quality is good, the work efficiency is high, and the integral setting and one-step in-position construction method is favorable for shortening the construction period and reducing the construction cost.
Description
technical field [0001] The invention relates to a construction installation project pipeline casing reservation, in particular to a one-time construction method for the overall shaping of the steel casing of the pipeline in the building shaft. Background technique [0002] Civil buildings are generally equipped with multi-channel piping systems such as water supply, drainage, fire protection, air conditioning, and heating. The vertical risers of these systems are mostly installed inside the building shaft. The internal space of the shaft is narrow, and various types of pipes cross each other greatly. Ensuring the installation accuracy and construction quality of the pipes passing through the floor casing is a common problem faced by construction and installation projects. [0003] At present, the pipe casing reservation of construction and installation projects generally adopts the construction method of first reserving the pipe hole and then burying the casing. That is, du...
